MACHINE FOR MARKING PATTERNS.

SPECIFICATION forming part of Letters Patent No. 462,331, dated November3, 1891.

Application filed December 13, 1890. Serial No. 374,533. (No model.)

To aZZ whom it may concern.-

Be it known that we, Isrnon A, SCHAEFFER and BARNETT SCHAEFFER, both ofthe city, county, and State of New York, citizens of the United Statesand England, respectively, have invented certain new and usefulImprovements in Machines for Marking Patterns, of which the following isa specification.

In a patent granted to us on December 30,

1890, No. 4%,798, a machine for marking patterns for garments wasdescribed, which consisted, essentially, of an exterior supportingframe,a cylindrical screen containing the marking-powder and having aperforated lower portion, a slide-frame for supporting said screen, saidslide-frame being guided in the supporting-frame, and means forimparting intermittent reciprocating motion to the cylindrical screenfor producing the dropping of the marking-powder from the same. Inaddition to these features, an inclined chute was arranged that extendedfrom the upper part of the guide-roller back of the screen into anopening at the top of the same, so as to-transfer the surplus powderback to the screen.

Since making the application for the patent referred to We have foundthat it is necessary for the proper working of the machine by whichpatterns are transferred, in connection with a perforated pattern sheetor chart to cloth or other fabrics, to provide certain additionalelements, inasmuch as the mere dropping of the marking-powder throughthe holes of the chart was not sufficient to properly affix the same tothe cloth. For the purpose of accomplishing this in a more eifectivemanner it is necessary to add to the elements of the machine asheretofore made by us a spring-actuated pressure-roller and rotatingfixing-roller, by which the marking-powderis pressed through theperforations of the marking-sheet into the cloth, so as to be retainedthereon; and for this purpose the present invention consists in certainimprovements on the marking-machine heretofore referred to by arranging,in connection with the same, a spring-actuated presser-roller and aroller provided with brush-like tufts or strips, whlch roller is rotatedby a suitable transmittinggearing from the front roller, and, inaddition thereto, a quickly-rotating brush at the rear end of themachine, by which the surplus powder is transferred into abox-likereceptacle back of said brush, as will be fully described hereinafter,and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of our improved machine for marking patterns oncloth. and other fabrics. Fig. 2 is a plan view of the same with aportion of the inclosing box broken away, so as to show the workingparts below the same. Fig. 3 is a side elevation of the gear-wheels bywhich motion is imparted to the fixing-roller and collectingbrush bywhich the marking-powder is pressed into the cloth and the surpluspowder collected.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents an oblong box, of sheet metal orother suitable material, which is provided with partitions at, havingopenings that form bearings for the different rotating parts of themachine. A handle A is applied to the top of the box A, by which themachine is readily moved in either direction. At the front end of theframe A is arranged a presser-roller C, and back of the same, at properdistances from each other, two additional rollers O and G are arranged,which are preferably made of wood and of sufficient weight to exert acertain pressure on the fabrics to be marked.

Immediately back of the front roller 0 is arranged a cylindrical screenD, which is supported by pivots d at its ends in a slide-frame D',Whichis guided by anti-friction rollers d in slots d of the partitions a ofthe box A. A pin (1 in each side of the slide-frame D is connected by aspiral spring (1* with a fixed support on the partition a, as shown inFig. 2, which springs serve to move the slide-frame D in forwarddirection. To the ends of the front or presser roller 0 are appliedfixed starwheels which are engaged by anti-friction rollers d at thefront ends of the slide-frame D, so that the teeth of said star-wheelsimpart an intermittent reciprocating motion to the slide-frame D andscreen D when the machine is moved forward over the fabric and theresser-roller O rotated thereby. The reciprocating screen D is formedof' two sec- I tions, a-main section D and a lid D which the cloth. Thescreen D is provided with two spring-hooks (:1 which are arranged closeto each other, but so as to extend in opposite direction, as shown inFig. 1. These springhooks serve to lock the screen D either in itsnormal position with the perforated portion at the lower part or withthe imperforate lid (1 at the bottom, in which position nomarking-powder can be dropped. The springhooks d engage transverseconnecting-rods d of the slide-frame D and permit. in connectiontherewith the ready locking of the screen in a position so as to dropthe marking-powder and in a position in which the dropping isinterrupted.

The marking-machine rests on the front presser-roller O and the rearroller C2, the intermediate roller 0' being acted upon by strong springsf f, that press on its pivots f, guided in vertical slots f of thepartitions a, so as to keep the roller 0 in contact with themarking-sheet, but permit it to give for any unevenness of theperforated sheet. The spring-pressed roller 0' serves to press thepowder dropped from the screen into the perforations of themarking-sheet onto the top layer of cloth preparatory to the fixing ofthe same by a brush-roller E, which is located between the rollers C andC and rotated in the same direction as the guide-roller G bymotion-transmitting mechanisms, which are arranged at each side of themachine and 0perated by the presser-roller O and longitudinal shafts g,that are supported in bracketbearings g of the partitions a a.

Bevel-wheels g on the shaft of the presserroller C mesh withbevel-Wheels g on the front ends of the side shafts g, which by two setsof additional bevel-wheels g g and g g transmit rotary motion to thebrush-roller E and a collecting-brush F at the rear end of the machine.The bevel-gears g and g are so arranged that a greater speed is impartedto the fixing-roller E and a still greater speed than that of thepresser-roller O to the collectingbrush F, which is accomplished byincreasing the size of the gear-wheels g g, as shown in Figs. 2 and 8;The roller E is provided with a number of strips or tufts e, of felt orother like material, which strips serve to press the powder that isdropped through the holes of the marking-chart into the cloth or otherfabric to be marked, so as to affix it thereto. The marking-powder thatstill remains on the perforated transfer sheet or chart 'is then takenup by the collecting-brush E, which is located back of the roller C andtransferred into a box-like receptacle G at the rear end of the machine.The bristles of the collecting-brush F also assist in fixing themarkingpowder passed through the holes of the marking-sheet on the toplayer of cloth. The re-' ceptacle G is provided with an inclined ledge Zat'its lower front part, along which the marking-powder is moved by thebrush F, so as to be deposited in the-box G. The markingpowder istransferred from time to time from the collecting-box G to the screen D,from which it is again dropped on the perforated transfer-sheet.

The sheet-metal inclosiug box A is provided with a hinged top lid abovethe screen D, as shown in Fig. 1, and with hinged rounded-off side boxesA that inclose the transmitting mechanisms at each side of themachine,as shown in Figs. 2 and 3. The side boxes A are locked inposition by hooks h h, which permit the ready opening of the side boxeswhen it is necessary. to gain access to the transmitting devices forrepairing or lubricating the same. By moving the marking-machine overthe perforated sheet or chart, by means of which the patterns are markedon the cloth or other fabric, the screen D is intermittentlyreciprocated bythe action of the front presserroller and theintermediate actuating mechanism between it and the screen D and by thesudden motion imparted to the screen the marki ng-powder dropped intothe holes of the sheet and then passed into the cloth by thefixing-roller B, so that the lines of the patterns are clearly affixedto the cloth or other fabric. The surplus marking-powder is transferredby the collecting-brush into the boxlike receptacle G at the rear end ofthe machine. The machine is guided along the cutting-table on which thelayers of cloth to be marked are supported by means ofdownwardly-extending rollers at one side of the machine, which rollersact as guiding and IOU IIO

steadying devices for the machine in its motion over the cloth to bemarked. The machine transfers the patterns from the perforated sheet ina quick and reliable manner to the fabrics that are to be out intogarments, so that a considerable saving in time and labor as compared tothe methods heretofore in use is obtained.

Having thus described our invention, we claim 1. The combination, withan exterior supporting-box and frame having guide-rollers, of a screenhaving a perforated lower portion, means for imparting an intermittentreciproeating motion to said screen, a fixing-roller arranged back ofsaid screen and having radial. feltstrips in its face, acollecting-brush at the rear part of the machine, and a box-likereceptacle back of the brush for collecting the surplus markingpowder,substantially as set forth.

2. The combination of an exterior box and frame, a number ofguide-rollers for supporting the same, a cylindrical distributing-screenhaving a lower perforated portion, a slideframe for supporting saidscreen, means for imparting an intermittent reciprocating motion to saidscreen, a fixing-roller arranged between the guide-rollers back of thescreen, a collecting-brush at the rear of the machine, a box-likereceptacle for collecting the surplus marking-po'wder back of the brush,and transmitting mechanism for imparting rotary motion from the frontguide-roller to the fixing-roller and collecting-brush, substantially asset'forth.

3. The combination of an exterior supporting-box and frame having afront and rear guide-roller, an intermediate spring-pressedguide-roller, an intermittently-reciprocating screen between the frontand intermediate guide-roller, a rotary fixing-roller between theintermediate and rear guide-roller, a collectin g-brush back of the rearguide-roller, and a collecting-box back of the collecting-brush at therear end of the machine, substantially as set forth.

4. In a pattern-marking machine, the combination of a reciprocatingslide-frame having transverse rods, with a cylindrical screen pivoted tosaid frame and having a perforated portion and a hinged lid, andspringhooks attached to said screen and extending in opposite directionsto each other, said hooks being adapted to engage one or the other ofthe transverse rods, according as the screen is to be set with theperforated portion at the lower or at the upper part of the same,substantially as set forth.

In testimony that we claim the foregoing as our invention We have signedour names in presence of two subscribing witnesses.
